Bicycle May Speed Up Parkinson's Diagnosis
Posted 7 Oct 2011 by Drugs.com
FRIDAY, Oct. 7 – A patient's ability to ride a bicycle can help doctors determine whether the patient has Parkinson's disease or atypical parkinsonism, regardless of the terrain or riding situation, a new study indicates. Atypical parkinsonism includes disorders that appear similar to Parkinson's disease but respond differently to treatment. It was already known that patients with atypical parkinsonism lose the ability to cycle early in their illness, while Parkinson's patients can still ride well. But it wasn't known if this "bicycle sign" was universally applicable across the varieties of riding environments or situations in different countries. In this study, Japanese researchers assessed the reliability of the "bicycle sign" in their country, which has hilly, narrow roads crowded with cars. They found that 88.9 percent of Japanese patients with atypical parkinsonism stopped cycling ... Read more

Berries May Offer Sweet Protection Against Parkinson's Disease
Posted 14 Feb 2011 by Drugs.com
SUNDAY, Feb. 13 – People who eat foods rich in antioxidants called flavonoids, especially berries, may be protecting themselves from developing Parkinson's disease, a new study suggests. In addition to berries, flavonoids are found in a variety of foods such as apples, chocolate, and citrus fruits. These compounds have been touted as protective against some diseases because of their antioxidant effects, researchers say. However, not all flavonoids are created equal. Only those known as anthocyanins, found in berries and other red/purplish fruits and vegetables, protected both men and women, according to the results of this study, which was funded by the U.S. National Institutes of Health. "Although it's too early to say that eating berries can reduce Parkinson's disease risk, benefits of berries have been reported in several previous studies, for example, lowering risk of ...

Using Light to Silence Harmful Brain Activity
Posted 6 Jan 2010 by Drugs.com
WEDNESDAY, Jan. 6 – New tools that use different colors of light to silence brain activity could lead to new treatments for disorders such as epilepsy, chronic pain, Parkinson's disease and brain injury, neuroscientists say. These so-called "super-silencers" provide precise control over the timing of the shutdown of overactive brain circuits, something that's impossible with existing drugs or other conventional treatments, according to the research team from the Massachusetts Institute of Technology. The research is published in the Jan. 7 issue of the journal Nature. "Silencing different sets of neurons with different colors of light allows us to understand how they work together to implement brain functions," study senior author Ed Boyden, a professor in the MIT Media Lab and an associate member of the McGovern Institute for Brain Research at MIT, said in a news release. "Using these ... Read more
